KemSep C-8402 Equivalent Screening (CNfloc C8001)
ChinaPAM can quote a cationic PAM powder screening route for a confirmed KemSep C-8402 enquiry, led by CNfloc C8001 with C8015 as the one backup. Dry polymer on both sides, medium-charge direction. Send the complete model name with its C- prefix or a bag-label photo and the enquiry opens. ChinaPAM accepts the enquiry, quotes the screening route, and discusses sample arrangements after the grade and conditions are confirmed.

Published reference data and the ChinaPAM route for Kemira KemSep C-8402
KemSep is a trademark of Kemira Oyj. ChinaPAM is an independent manufacturer and is not affiliated with, endorsed by, licensed by or a distributor for Kemira. The brand and grade names are used only to identify the incumbent product a buyer is asking about. Charge and molecular-weight descriptors in the held sources are relative labels inside one supplier’s own range. They carry no calibrated numeric relationship to any other supplier’s labels and cannot be converted between ranges. Our products are separately branded ChinaPAM grades and are not licensed copies.
| Parameter | ChinaPAM Supply Route | Kemira KemSep C-8402 |
|---|---|---|
| Product form | Cationic polyacrylamide powder (CNfloc C8001, backup C8015) | Cationic dry polyacrylamide (DPAM), listed for mud dewatering in World Oil 2015, p.21, and placed in the KemSep 8000 dry series by the mirrored brochure |
| Charge position | C8001 is the medium-charge lane on the ChinaPAM scale; C8015 is the single backup | Described as medium charge in the brochure product table, between a low-charge and a high-charge member of the same series. Charge and molecular-weight descriptors in the held sources are relative labels inside one supplier’s own range. They carry no calibrated numeric relationship to any other supplier’s labels and cannot be converted between ranges. |
| Molecular-weight position | Confirmed from the quoted ChinaPAM grade’s own data at quotation | Described as medium molecular weight in the same table, again as a relative label |
| Sibling separation in the source | ChinaPAM screens C-8402 from the medium-charge lane; the low-charge sibling starts from its own charge band and is assessed separately. | The brochure table separates the series into low-, medium- and high-charge members, so the members are not interchangeable within it |
| Source status | Current ChinaPAM grade data, read against the grade being quoted | A historical mirrored document, used for series placement and relative position and not treated as a current commercial specification |
| Formulation | A separately branded ChinaPAM grade | Unknown. No identical-formula or drop-in claim is made in either direction. |
| Current availability | Confirmed in the quotation against grade, destination and order conditions | Current Kemira supplier and manufacturer status for the branded grade is recorded as unknown in the held sources, and so is current availability on either side. ChinaPAM makes no statement about the branded product’s present specification. |
| Documents | Applicable document set and TDS availability are confirmed against the quoted ChinaPAM grade; a batch-specific COA is tied to a confirmed shipment only. Price, current stock, lead time and sample dispatch are agreed in the quotation, not stated from the source documents. | A trade-press listing and a mirrored historical brochure table. Neither is a current specification. |
Specifications

| Acceptance Basis | Measured charge demand plus a controlled dose ladder on the actual feed |
Key Features
- Medium-charge position stated explicitly; low- and high-charge members of the same dry series are assessed as separate requirements.
- Powder-to-powder route: no emulsion conversion, so the open questions are charge demand and dissolution
- Series placement published with its provenance named — a mirrored historical brochure, not a current datasheet
- Charge band treated as a decision rather than a label: if neither rung passes, the band decision is reopened instead of equivalence being claimed
- Approved make-down window published so a dry-route trial is not invalidated before it starts
- Two documented failure modes with their verification steps
- C- prefix and complete model name carried through unchanged
Applications
- Drilling-mud dewatering qualification where the incumbent is a dry cationic PAM named KemSep C-8402
- Medium-charge dry-polymer procurement from a bag label, TDS or tender line carrying the complete model
- Charge-band re-checking where a low- or high-charge grade was substituted without a demand measurement
- Make-down validation where undissolved polymer has already been seen in the dosing line
- Model-identity control where repeated purchase requests or closely numbered series members risk being mixed.

The supply answer first: C8001 leads, C8015 backs it up
A confirmed KemSep C-8402 enquiry gets a cationic PAM powder screening route from ChinaPAM, with CNfloc C8001 screened first as the medium-charge lane and CNfloc C8015 as the single backup. Dry polymer on both sides, so the form question is already settled and the trial can go straight at charge demand and dissolution.
The state is same-type screening. ChinaPAM does not claim to supply the branded KemSep grade and offers no drop-in replacement for it. Where both candidates sit in the same band, the primary-and-backup ordering reflects available ChinaPAM grade data and the order of the sources rather than demonstrated superiority.
ChinaPAM accepts the enquiry, quotes the route, and discusses sample arrangements after the grade and conditions are confirmed. Price, current stock and delivery timing belong to the quotation and are not asserted from the source documents.
Identity lock: medium is a position, not a preference
The C- prefix stays on the model name through the whole enquiry. This matters more here than on most pages, because the brochure table splits the same dry series into a low-charge, a medium-charge and a high-charge member, and the only thing separating them in a purchase order is a short string.
A bag-label photograph settles identity faster than a retyped name. Where the buyer holds a current TDS, it is read alongside the label. Siblings remain separate requirements, and a closely numbered neighbour is assessed by its own charge position and application conditions.
Several purchasing enquiries naming the same model can still refer to one requirement. Confirm the end user, duty and operating conditions before treating them as separate projects or combining them.
Three facts the held sources actually establish
The provenance is named on every row, including where a row rests on a historical mirror rather than a live document.
| Fact | Where it comes from | What it does not establish |
|---|---|---|
| C-8402 is a cationic dry polyacrylamide (DPAM) listed for drilling-mud dewatering. | World Oil, 2015, page 21. | Form and duty family only — no charge figure, no MW figure, no performance claim. |
| A mirrored Kemira-origin brochure places C-8402 in the KemSep 8000 dry-PAM series. | Mirrored brochure, page 2 product table (historical mirrored document). | Series membership only. A historical mirror is not evidence of the current commercial specification or of present availability. |
| The same brochure table describes it as cationic, medium charge, medium molecular weight, with a low-charge and a high-charge member listed separately in the same series. | Mirrored brochure, page 2 product table. | Relative labels inside that brochure’s own range. They establish no cross-vendor numeric equivalence and cannot be converted into ChinaPAM values. |
What is matched, what stays open, and the intake that narrows it
Ion type and form are matched, and the charge direction is readable. Numeric alignment, formulation and process performance are not established and stay recorded as unknown and test-required.
Useful intake: feed source, solids percentage, pH, temperature, conductivity or salinity, the biological-versus-primary solids share where it applies, the incumbent active dose on an active-polymer basis, the current make-down concentration and maturation time, the dewatering equipment, and the acceptance targets. A measured charge demand is the single most valuable number a buyer can bring to a medium-charge enquiry.
The complete label alone opens the enquiry. The rest sharpens the route and the trial design.
Preparation: dissolution before dosing, every time
A matched form removes the inversion problem, not the dissolution problem. Dry polymer dosed before it has fully dissolved, or made down at an unvalidated concentration, produces a dose response that drifts for reasons that have nothing to do with the chemistry.
ChinaPAM powder preparation runs at a 1–3 g/L recommended window, 5 g/L maximum, and no longer than 60 minutes at working concentration. Preparation concentration is not process dosage.
Each product is prepared under its own applicable instructions and the comparison is normalised to active polymer. Preparation concentration is not process dosage.
Two failure modes, and the check that catches each one
The second of these is specific to a medium-charge target sitting between two siblings, and it is the one that quietly wastes the most polymer.
| Trigger | Consequence | Verification step |
|---|---|---|
| Dosing starts before dissolution is complete, or at a make-down concentration that was never validated. | Undissolved polymer reaches the process, the dose response becomes unstable and the trial result stops being readable. | Make down inside the approved 1–3 g/L window, 5 g/L maximum, under 60 minutes; confirm complete dissolution and pump delivery before recording any treatment result. |
| The medium-charge duty is treated as interchangeable with its low- or high-charge siblings in the same series. | Either under-neutralisation or charge reversal, both of which cost filtrate quality and polymer at the same time. | Screen C8001 first and C8015 as the backup against a measured charge demand. If neither passes, reopen the charge-band decision rather than claiming equivalence. |
Trial design, acceptance metrics and the go/no-go rule
Both products run on the same feed, the same equipment and the same time window, on an active-polymer basis, across a controlled dose ladder rather than a single point.
Acceptance metrics are agreed up front: the settling or dewatering measure that governs the duty, filtrate turbidity, captured solids, cake dryness, throughput, active dose and handling. Failing conditions are recorded as carefully as passing ones.
If identity, form or acceptance data conflict, the proposed route is rejected and the requirement is checked again against the original model, duty and trial target before another route is offered. Applicable document set and TDS availability are confirmed against the quoted ChinaPAM grade; a batch-specific COA is tied to a confirmed shipment only. Price, current stock, lead time and sample dispatch are agreed in the quotation, not stated from the source documents.
Brand Equivalents & Replacements
A confirmed KemSep C-8402 enquiry is screened against ChinaPAM’s own medium-charge cationic powder lane, CNfloc C8001, with C8015 as the single backup. ChinaPAM takes the enquiry, screens on the held documents and your application conditions, quotes, and discusses sample arrangements from there. The held brochure labels are relative to their own scale, so the dose window and filtrate result are only confirmed by a trial on your feed — not asserted here as a tested replacement or guaranteed equivalent.

Frequently Asked Questions — KemSep C-8402 Equivalent Screening (CNfloc C8001)
Can ChinaPAM supply for a KemSep C-8402 requirement?
Yes — as a same-type cationic powder screening route led by CNfloc C8001, with CNfloc C8015 as the single backup. The complete model name including the C- prefix, or a bag-label photo, opens the enquiry. ChinaPAM does not claim to supply the branded KemSep grade and offers no drop-in replacement for it.
Why does the medium-charge position matter so much here?
Because the brochure table itself separates this dry series into low-, medium- and high-charge members. A source that distinguishes its own grades by charge is telling you the charge band is load-bearing. Screening a medium-charge duty from a low- or high-charge starting grade therefore changes the chemistry the buyer asked for, and it usually shows up as either under-neutralisation or charge reversal.
What happens if neither C8001 nor C8015 passes?
The charge-band decision gets reopened with the measured charge demand in hand. What does not happen is a third and fourth substitution dressed up as the same route, or an equivalence claim used to close the gap. A clean negative result with recorded conditions is more useful to a buyer than a forced pass.
Can the medium charge label be matched to a ChinaPAM figure?
No. Low, medium and high in that table are positions inside one supplier’s own range. Charge and molecular-weight descriptors in the held sources are relative labels inside one supplier’s own range. They carry no calibrated numeric relationship to any other supplier’s labels and cannot be converted between ranges. C8001 is screened first because it is the medium-charge lane in the ChinaPAM range, which is a direction, not an equivalence.
We have several enquiries naming this grade. Are they different requirements?
Usually not. Multiple purchasing leads naming the same model may refer to one requirement, so confirm the end user, duty and operating conditions before treating them separately. A closely numbered neighbour is a different grade and requires its own charge-band and application review.
What is confirmed in the quotation, and what is not stated here?
The quotation confirms the screening route, sample arrangements, the applicable document set, packing and delivery against your selected grade, destination and order conditions. Applicable document set and TDS availability are confirmed against the quoted ChinaPAM grade; a batch-specific COA is tied to a confirmed shipment only. Price, current stock, lead time and sample dispatch are agreed in the quotation, not stated from the source documents.
